Petra has a truly international background: she holds a Swiss passport, was born in Germany and grew up in South America. For as long as Petra can recall, she has had a passion for wildlife and remote places. She became a zoologist and soon found out that she was especially interested in marine mammals. Her Master thesis was carried out in an isolated natural reserve in Patagonia where she studied southern sea lions. Petra also participated in research projects on Minke whales in the Hebrides, on dolphins in the Mediterranean and sperm whales in Norway. Recently, she has been working for the Whale and Dolphin Conservation Society at its Wildlife Centre in Scotland.
